T0 all eti/1.0m it may concern.'

Be it known that I, DANIEL SALAZAR, a citizen of Colombia,'SouthAmerica, residing at Medellin, Colombia, South America, have invented acertain new and useful Improvement in Systems of DistributingElectricity and Apparatus Therefor, of which the following is a full,clear, and exact def scription.

My invention relates to improvements in systems of distributingelectricity and apparatus therefor, and has for its object to produce asystem in which groups of translating devices are controlled from asingle point through a succession of switching means, each group havinga controlling switch which cuts in and out the translating devices ofsaid group and also controls the next succeeding switch.

It further has for its object to provide such a system in which all of aplurality of successively acting switching devices are controlled by asingle time operated switch.

It further has'for its object to provide a special switch for use insaid system.

A further object of my invention is to provide a combined house lightingand street lighting system in which a plurality of groups of streetlights or other translating devices are controlled by a series ofinterrelated switches which cut in and out of circuit by the opening andclosing of the first switch of the series.

A further object of my invention is to provide an alternating currentsystem in which the above objects are obtained.

The following is a description of an embodiment of my inventionreference being had toV the accompanying drawings, in which,-

Figure 1 shows a plan View of the preferred form of switch;

Fig. 2 shows a section of the same on the line 2-2 of Fig. 1;

Fig. 3 shows a diagram oi my improved system `the individual groupsbeing connected in circuit, and f Fig. 4 shows the position of the firstswitch when the groups are cut out of circuit.

. Referring more particularly to the draw.- ings Fig. 1 shows a switchhaving a base 2 upon which are mounted circuit terminals 4, 6 and 8which are respectively connected to switch contacts 10, 12 and 14 asshown Serial No. 541,875.

diagrammatically in Fig. 3. Upon this base are also mounted circuitterminals 16, 18 and 20 which are respectively connected to switchcontacts 22, 24 and 26 as shown in Fig. 3. 28 is a switch arm carried bya bar 30 pivoted at 32. This switch arm is always electrically connectedto terminal 4 and is adapted to electrically connectk either thecontacts 10 and 12 or the contacts 12 and 14. 84 is another switch armmounted upon a bar 36 pivoted at 38r and adapted to make electricalconnection between either the contacts 22 and 24 or 24 and26. The bars82 and 36 are connected by toggle levers 40 and 42 to a sleeve 44carried by a magnetic core 46. The ends of this magnetic core aresurrounded'by solenoids 48 and 50 mounted upon the base 2. The solenoid50 is elec* trically connected between the terminal 4 and contact 10 andthe solenoid 48 is electrically, connected between the terminal 8 andcontact 14. When the solenoid 50 is euergized the parts are moved to theposition shown in Figs. 1 and 3. When the solenoid 48 is energized thecore 46 is moved in the other direction to the position shown in Fig. 4so that the switch arms 28 and 34 electrically connect the switchcontacts 12 and 10 and the switch contacts 24 and 26 respectively forthe purposes hereinafter referred to.

Referring to Figs. 3 and 4, 100 is an alternating current generator tothe supply mains of which transformers 102, 104, 106 and 108 areconnected in multiple. The secondaries of the transformers 104, 106 and108 supply work circuits containing translating devices 104', 106 and108 respectively, which may be considered to be house lights or thelike. Because of the multiple arc arrangement ofthe system thesesecondary work circuits are independent of one another. The secondary ofthe transformer 102 is connected to the terminal 6 of the iirst switchand to a revolvable contact member 110 operatedkby' a suitable timeclock 112. This contact member 110 is adapted to engage and disengagecontacts 114 and 116 which are respectively connected to the terminals 8and 4 of the first switch. The terminal 20 of each preceding switch isconnected to the terminal 8 of a succeeding switch and the terminal 18of each switch is connected to oneiof its respective branch mains at118. The terminal 16 of each suc- CTL ceeding switch is connected to onemain o'l the corresponding group work circuits 1042, 1062 and 1082 whoseother main is connected to the second main of a branch circuit at anydesired point thereof, for instance 120. The terminal 4 of eachsucceeding switch is con nected to the same main of the. group as theterminal 16 of the preceding switch andat any desired point. ln carryingout my invention this connection is usually made at a pointbeyond someor all ollthe translating devices inthe group circuit, such tor instanceas atzthe point 122.-

With. this arrangement thev operation is as follows: Y

rlie alternating current. generator 100 generates a relatively highpotential cur rent which is transformed by the translforniers 104, 100.andl ano. deliveredlto the translating devices 104, 106. and 108 in themanner ordinarily employed in the well known multiple arcv alternatingcurn rent system, The. transformer 102 supplies energy by its secondarycircuit which is controlled by the time actuated contact 110. As will beseen this seconda-ryV circuit is normally open.

With the 4parts in the posit-.ion shown in Fig. 3 the membery 110 movesclockwise. The contact .114 supposedto be engaged by the contact 110-atadefinite hour, suoli as six` oclock a. m. The contact 116 is supposedto be reached `at a deiinite hour,

such as eight oclockp. m. the member 110 reiolving-once in twenty :tourhours. rlhe positions of the-contacts 114 and 116 may be made such thatthey Ywill' correspond vto anyV desired hours. When the switch arm 110rea-ches the contact 114 it closes acircuit through' a.y seconda-ryoithe transformer 102the switch arm 2S and the solenoid `48.`

This causes therore 46 ltomove so as to cause the switch arm 34'to breakits engage ment with thecontact 22 and makev engagenient with 'theContact 2G which cuts the group 1042 out of circuit.V It' also moves theswitch arm, QS out ot engagement with the contact 14 and into,engagement with the contactlO so that when 'the contact arm 110 reachesthe contact 116 a -current will bek passedl through the solenoid 50 ofthe lirst switch restoring theparts to the position shown in Fig. 3.

The engagement of ythe switch arm 34 of the first switch with itscontact 26 establishes a circuit through the solenoid 48 of the secondswitch causing' that switch to operate in the: same manner in which thefirstv actua-ting current is closed it actuates a switch and isimmediately opened by that switch so that normally all of the actuatingcircuits are open, being momentarily closed ior actuating purposes. Itis further to be noted that inasmuch as the terminals 6 and 1S ofadjacent switches can be connected to the branch mains supplying thesame house lights at any desired point and inasmuch as the cont-acts 4of allexcept the first switch can be connected at any desired lpoint tothe Amain of the proper group, thel secondV and all subsequent switchescan be located at a considerable distant from the irst switch and fromVeach other, the branch and group mains carrying lighting current beingused to establish the inter-switch vconnections with the exception offthe single connection between terminals 20 and 8 of adjacent switches.It is there-fore necessaryl to have but one controlling connectionfwhichis of any considerable length and as above stated this controllingconnectionis normally out olcircuit and when in circuit carries, currentonly momentarily.

The position shown` inY Fig. 4 corresponds to that when the grouptranslating devices areout of circuit.

By rising this arrangement in which the lighting circuits are used orthemost part to establish controlling circuit-s for succes sive switchesandy in which the eXtei'ided connection between two succeeding switchesderives its current from the work circuit supplying the group controlledby the preceding switch there are no `controlling circuits oli-higherpotentialthan the working potential and there are no controlling magnetsor solenoids which are in series so as to introduce resistance or`indue-tance Vwhich will interfere with the action oi any vother solenoidor magnet. The system therefore, overcomes many of the defects ofsystems which have'heretofore been` in use presenting a multiple arcsystem for street light ing with a simple'and effective control andeliminating a'speeial series controlling circuit, and anyV specialswitch controlling-'circuit in'which currentl is normally passing forany considerable period.
